Short-timescale Variability in the Broadband Emission of the Blazars Mkn421 and Mkn501

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/14350We analyse ASCA x-ray data and Whipple γ-ray data from the blazars Mkn421 and Mkn501 for short-timescale variability. We find no evidence for statistically significant (>3σ) variability in these data, in either source, on timescales of less than \sim 10 minutes.Submitted to ICRC, 4 pages, 4 figuresAstrophysicsShort-timescale Variability in the Broadband Emission of the Blazars Mkn421 and Mkn501text
